Don't you want that non-null column to be a foreign key ?

Hello everyone,
After some time of operation (a day or so), from time to time I'm
getting this error:
TimeoutError: QueuePool limit of size 5 overflow 10 reached, connection

I have to stress that not much activity is taking place on that OS as it

Since removing them entirely is an option for you, perhaps just completely
remove them from search engines

That's what a foreign key is used for: http://en.wikipedia.org/wiki/Foreign_key

I have three tables:

Hi there,
I am working with SqlAlchemy for the first time (coming from
SqlObject), and I fear I may not understand it as well as I thought I

I've had quite the opposite experience with SQLAlchemy's
documentation, and I just started using it for a couple of small
projects about two weeks ago. Once I was accustomed to the site
layout, it became reasonably easy to find what I was looking for.
Specifically, I've been using the integrated

The simplest thing to do is to append:
Disallow: /docs/04/
Disallow: /docs/03/
agreed, this is done.

I know that PostgreSQL can't continue in a transaction after an error, you
have to roll back the transaction. I don't know what the SQL standard says

they don't have an attribute called version. i think you want

that means min_version and max_version aren't columns.I guess you're
looking for Version.version, in which case you probably need to JOIN to
that table twice on both the min_version and max_version. write (and
test) the query you want in SQL first to get an idea for what you're
doing.
